[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0037] Reference Figure 1 to Figure 5 , which is the first embodiment of the present invention, comprises a fresh air wall-mounted jet air conditioning unit, comprising an air conditioning box 300, and a plurality of spherical air outlets 301 arranged on the air conditioning box 300, and further comprising,

[0038] The fixing unit 100 includes a fixing component 101 disposed in the spherical air outlet 301, a driving component 102 threadedly connected to one side of the fixing component 101, four groups of supporting components 103 distributed in an annular manner on the fixing component 101, and the ends of each group of supporting components 103 extend outward to the driving component 102, a rubber ring 104 sleeved on the outer ring of the fixing component 101, and the rubber ring 104 is located between the spherical air outlet 301 and the fixing component 101, and four groups of ventilation holes 105 evenly arranged in an annular manner on the fixing component 101; and, because of its special structure, the spherical air outlet 301 It can be rotated and adjusted at multiple angles, and the air outlet direction can be adjusted according to actual needs. The fixing unit 100 is vertically arranged between the air outlet of the spherical air outlet head 301 and the channel connected to the inside of the air-conditioning box 300 to block the connection between the two. The supporting component 103 is slidably inserted on the fixing component 101. The rubber ring 104 is located at the position where the edge of the fixing unit 100 and the spherical air outlet head 301 abut against each other, which can ensure the sealing of the connection between the two. The vent 105 is in a state of being connected on both sides. The airflow inside the air-conditioning box 300 can enter the spherical air outlet head 301 through the vent 105 and be discharged outward.

[0039] The shift unit 200 includes a push component 201 which is laterally inserted into the axial position of the fixed component 101, a dust-proof component 202 which is sleeved on the push component 201, and one side of the dust-proof component 202 extends into the fixed component 101, a diffuser component 203 which is sleeved on the outer end of the dust-proof component 202, and a driving motor 204 which is arranged on one side of the top end of the dust-proof component 202, and the inner end of the driving motor 204 is meshed with the outer side of the center of the diffuser component 203, and the push component 201 and the fixed component 101 are connected. The pushing component 201 is in a sliding connection relationship, that is, the pushing component 201 can freely telescope and slide in the axial direction of the fixed component 101, and the dustproof component 202 is in a rotational connection relationship with the fixed component 101. The dustproof component 202 is coaxial with the fixed component 101, and the diffuser component 203 is also coaxial with the dustproof component 202, and the diffuser component 203 can rotate in a circle with the dustproof component 202 as the axis. The driving motor 204 is fixedly connected to the dustproof component 202 and can move synchronously with the dustproof component 202.

[0040] Among them, combined Figure 4The fixing component 101 includes a threaded shaft 101a which is hollow inside and has threads on the outer wall, and the driving component 102 is threadedly connected to the threaded shaft 101a, a limit pin 101b is horizontally arranged inside the threaded shaft 101a, four groups of baffles 101c are annularly distributed on the outside of the top of the threaded shaft 101a, and the vent 105 is located between every two groups of baffles 101c, a limit groove 101d is provided in each group of baffles 101c, and the supporting component 103 is correspondingly inserted in the limit groove 101d, a slide groove 101e is provided on one side of the baffle 101c, and the two ends are respectively connected to the limit groove 101d and the outside of the baffle 101c, and a card slot 101f is provided on the edge of the baffle 101c, and the rubber ring 104 is sleeved on the card slot 101f.

[0041] During use, since the air outlet channels in the prior art are mostly circular tube structures, the four groups of annularly distributed baffles 101c can abut against the inner wall of the air outlet from directions, thereby achieving the purpose of installing the fixing unit 100 from multiple directions. The driving component 102 is connected to the threaded shaft 101a by a threaded connection, and the limiting groove 101d and the sliding groove 101e provide space for installing the supporting component 103, so that the supporting component 103 can be retracted in the baffle 101c to reduce its occupied space, and the card slot 101f is opened on the edge of the baffle 101c for being sleeved on the limiting rubber ring 104.

[0042] Further, combined with Figure 4 The baffle 101c as a whole has a fan-shaped structure of one eighth of a circle, that is, eight groups of fans identical to the baffle 101c can be combined and spliced ​​into a complete disc structure. The four groups of baffles 101c are evenly distributed so that the vents 105 located between every two groups of baffles 101c are also fan-shaped, and the shape and size of the fan correspond to the size structure of the baffle 101c.

[0043] Among them, combined Figure 4 The driving component 102 includes a threaded sleeve 102a threadedly connected to the threaded shaft 101a, four groups of arc frames 102b annularly distributed on the outside of the threaded sleeve 102a, the arc frame 102b is an arc structure and the inner end of the arc structure is fixedly connected to the threaded sleeve 102a, and an arc groove 102c is opened on the arc frame 102b, and one end of the support component 103 extends horizontally into the arc groove 102c.

[0044] During use, when the threaded sleeve 102a rotates on the threaded shaft 101a, the arc frame 102b will be driven to rotate synchronously, and one end of the arc frame 102b is fixedly connected to the threaded sleeve 102a, and the other end is away from the threaded sleeve 102a. Therefore, the object located in the arc groove 102c can move with the arc frame 102b when the threaded sleeve 102a rotates, or slide along the arc groove 102c to make way.

[0045] Among them, combined Figure 4 The supporting component 103 includes a supporting rod 103a that is matched and inserted into the limiting groove 101d, a limiting shaft 103b that is vertically arranged at the inner end of the supporting rod 103a, and the limiting shaft 103b extends outward through the sliding groove 101e to the arc groove 102c, and a top plate 103c that is fixedly connected to the outer end of the supporting rod 103a and has a fan-shaped structure.

[0046] During use, the support rod 103a is located in the limit groove 101d so that it is limited by the limit groove 101d, so it can only telescope and slide in the limit groove 101d and cannot detach from it, while the limit shaft 103b is doubly limited by the slide groove 101e and the arc groove 102c. The top plate 103c has a fan-shaped structure, and the larger arc edge of the fan is located on the outside. The larger arc edge can increase the contact points with the arc-shaped inner wall of the spherical air outlet 301, thereby further increasing the stability of the fixed unit 100 when installed in the spherical air outlet 301.

[0047] In summary, the fixing component 101 of the device is placed vertically in the spherical air outlet 301. Due to the spherical structure of the spherical air outlet 301, combined with Figure 2 The spherical structure has a plurality of circular cross-sections with different diameters. When the fixing component 101 is brought close to the air outlet of the spherical air outlet 301, the fixing unit 100 will be stuck on the circular cross-section with the most matching size. Then, the driving component 102 is rotated, and the driving component 102 drives the supporting component 103 to move through the arc frame 102b. Since the supporting component 103 is limited by the limiting groove 101d through the supporting rod 103a and the limiting shaft 103b, the rotating driving component 102 will push the limiting shaft 103b outward through the arc groove 102c on the arc frame 102b, and the limiting shaft 103b will push the supporting component 103 to extend outward as a whole, toward The outwardly extended support component 103 will firmly press the rubber ring 104 located on the outer ring of the fixing component 101 against the inner wall of the spherical air outlet 301. The rubber ring 104, which is subjected to the double pressure of the top sheet 103c at the top of the support component 103 and the inner wall of the spherical air outlet 301, will deform. The deformed rubber ring 104 can increase the contact area with the spherical air outlet 301, thereby enhancing the stability of the fixing unit 100 during installation. The four groups of support components 103 move synchronously, and the fixing unit 100 can be fixed from the inside to the outside between the spherical air outlet 301 and the air outlet from four directions, further enhancing the stability of the fixing unit 100 during installation.

[0048] Furthermore, the reason for using the above method for fixing is that the air-conditioning units in the prior art have been widely popularized, that is, the spherical air outlet 301 corresponding to the air-conditioning units has been produced and fixed. The present device adopts an independent structure and can be installed and fixed in the original spherical air outlet 301 through the fixing unit 100. There is no need to produce a new spherical air outlet 301 for matching. At the same time, the structure of the original spherical air outlet 301 will not be destroyed during the installation process, which can effectively reduce the production cost. At the same time, all spherical air outlets 301 whose diameter values ​​include the diameter of the fixing unit 100 can be matched and applied by the present device, and can meet the needs of being applied to spherical air outlets 301 of different specifications, thereby improving the applicability of the device. Example

[0049] Reference Figures 5 to 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that, without affecting the normal air supply operation of the air-conditioning unit, the air outlet is blocked to prevent external dust and impurities from entering the interior of the air-conditioning unit, thereby ensuring the safe use of the unit.

[0050] Compared with Example 1, further, the pushing component 201 includes a connecting shaft 201a laterally inserted on the axial center line of the threaded shaft 101a, a wind shield 201b arranged at one end of the connecting shaft 201a, a limiting plate 201c arranged on the connecting shaft 201a, a spring 201d sleeved on the lower end of the connecting shaft 201a and located on the side of the limiting plate 201c, three groups of transfer beads 201e equally divided in annular shapes on the outer end of the connecting shaft 201a, and a rectangular groove 201f opened vertically on the outer end of the connecting shaft 201a, and the limiting pin 101b is located in the rectangular groove 201f.

[0051] During use, the connecting shaft 201a is inserted into the threaded shaft 101a, and the limiting pin 101b passes through the rectangular groove 201f, which can limit the connecting shaft 201a in the circumferential direction, so that the connecting shaft 201a can only slide horizontally along the axis of the threaded shaft 101a. The wind shield 201b is a disc structure as a whole, and the wind shield 201b is coaxial with the connecting shaft 201a, and is located vertically in the spherical air outlet 301. The larger disc structure can increase the area of ​​air flow circulating in the spherical air outlet 301, and the two ends of the spring 201d are respectively abutted between the dustproof component 202 and the limiting plate 201c, and the pushing component 201 is always supported outward as a whole through elastic support.

[0052] Among them, the dust-proof component 202 includes a sleeve shaft 202a sleeved on the connecting shaft 201a, and the outer end of the sleeve shaft 202a extends into the threaded shaft 101a, four groups of partitions 202b are equally divided in annular shape on the outside of the sleeve shaft 202a, and the size and shape of the partitions 202b match the vent 105, two groups of limiting rings 202c are arranged on the top of the inner end of the sleeve shaft 202a, and the diffuser component 203 is rotatably sleeved between the two groups of limiting rings 202c, and three groups of guide grooves 202d are spirally coiled on the inner wall of the sleeve shaft 202a, and the transfer beads 201e extend into the guide grooves 202d.

[0053] During use, the size of the partition 202b is the same as that of the baffle 101c, so the dustproof component 202 and the fixed component 101 are staggered and overlapped to form a disc cross-section. The sleeve shaft 202a is rotatably connected to the threaded shaft 101a as a whole, and is maintained on the side of the threaded shaft 101a through the elastic support of the spring 201d. The guide groove 202d is spirally coiled on the inner wall of the sleeve shaft 202a (as shown in Figure 8), and the number of spiral turns is 0.225. From a top-down perspective, it can be seen that the two ends of the guide groove 202d are on the same circle, and the arc distance between the two ends is 45°. Since the transfer bead 201e is located in the guide groove 202d, the two can transmit pressure from each other to each other.

[0054] In summary, after the device as a whole is installed in the spherical air outlet 301 through the fixing unit 100, when the air conditioning unit is in an idle state, the spring 201d elastically expands outward, and the connecting shaft 201a is in a state of extending outward from the sleeve shaft 202a, and at this time, the partition 202b and the baffle 101c are staggered, and the outer ring of the partition 202b blocks and overlaps on the vent 105, cutting off the connection between the inside of the spherical air outlet 301 and the inside of the air conditioning unit, thereby achieving the purpose of preventing external dust and impurities from entering the interior of the device;

[0055] When the air conditioning unit is working and delivering air to the outside, the airflow from the inside will directly contact the wind shield 201b. Since the cross-sectional area of ​​the pushing component 201 is large, it will be subjected to a large blowing pressure. At this time, the pressure on the wind shield 201b is greater than the elastic supporting force of the spring 201d, which will drive the pushing component 201 to move outward as a whole. During the movement, the pushing component 201 can only slide in translation due to the limitation of the limiting pin 101b. The translationally sliding connecting shaft 201a will be blown by the wind through the adapter bead 201e. The pressure is transmitted to the dust-proof component 202. After the dust-proof component 202 is subjected to the pressure from the pushing component 201 moving outward, the horizontal pressure is converted into a thrust in the circumferential direction through the spiral guide groove 202d. As the pushing component 201 continues to move, the adapter bead 201e can eventually drive the dust-proof component 202 to rotate as a whole through the cooperation with the guide groove 202d. The rotating dust-proof component 202 will take the partition plate 202b away from the vent 105. At this time, the airflow can be normally transported to the outside through the vent 105.

[0056] When the pushing component 201 moves, the transfer bead 201e moves from the top of the guide groove 202d to the other end. Due to the guidance of the spiral turns of the guide groove 202d, the dustproof component 202 deflects 45 degrees. After the deflection, the partition plate 202b overlaps with the baffle plate 101c, and the vent 105 is in the maximum open state.

[0057] When the air flow stops, the pressure on the wind shield 201b disappears, and the spring 201d rebounds, pushing the pushing component 201 to reset, and during the resetting process, it pushes the dust-proof component 202 to rotate in the opposite direction, so that the reverse rotating dust-proof component 202 is re-sealed on the vent 105, and only isolation and dust-proof work needs to be performed.

[0058] The remaining structures are the same as those of Example 1. Example

[0059] Reference Figure 10 to Figure 13 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the purpose of adjusting the air outlet mode is achieved by adjusting the position of the diffuser component 203 to meet more usage requirements.

[0060] Compared with Example 2, further, the diffuser component 203 includes a ring 203a that is sleeved on the inner end of the sleeve shaft 202a and located between two groups of limit rings 202c, four groups of diffusers 203b that are equally divided on the outer ring of the ring 203a, and the diffuser plates 203b are provided with multiple groups of holes, and multiple groups of teeth 203c are distributed in annular shapes on the outer end surface of the ring 203a, and the teeth 203c are perpendicular to the ring 203a, and the structural dimensions of the diffuser plates 203b match the vents 105.

[0061] During use, the diffuser component 203 is rotatably connected to the sleeve shaft 202a through the collar 203a. The diffuser plate 203b overlaps with the partition plate 202b under normal conditions. The holes opened on the diffuser plate 203b can cut the airflow. The teeth 203c are located at the edge of the collar 203a and do not contact the limit ring 202c on the sleeve shaft 202a, so it will not hinder the diffuser component 203 from rotating on the dustproof component 202.

[0062] The driving motor 204 is fixedly mounted on the top side of the sleeve shaft 202a, and the gear 204a extends toward the diffuser component 203 to where the gear 204a is provided, and the gear 204a meshes with multiple sets of teeth 203c on the sleeve ring 203a.

[0063] During use, the driving motor 204 is fixedly connected to the sleeve shaft 202a, and can move along with the dustproof component 202 when it rotates. At the same time, through the engagement of the gear 204a with the teeth 203c, the driving motor 204 can drive the dispersion component 203 to rotate around the dustproof component 202 as the axis.

[0064] In summary, according to actual needs, the driving motor 204 drives the diffuser component 203 to rotate, and different rotation amplitudes of the diffuser component 203 can bring different airflow conveying effects;

[0065] When the diffuser 203 remains different, the diffuser 203b, the partition 202b and the baffle 101c overlap, and at this time, there is no shielding on the vent 105 (as shown in FIG10 ). At this time, the airflow column discharged through the vent 105 is thick, the airflow outlet area is large, and the wind speed is low, so a larger range of space can be cooled. We call the airflow discharged through the complete vent 105 the primary airflow;

[0066] When the diffuser component 203 rotates 45 degrees, the diffuser plate 203b will completely cover the vent 105, and completely separate the airflow passing through the vent 105 (as shown in FIG12). At this time, the airflow is completely cut into fine airflow columns by the holes of the diffuser plate 203b. The airflow at this time is called secondary airflow. The airflow columns of the secondary airflow have a smaller diameter and a relatively larger number, so that the airflow is divided into smaller parts, and the air columns are more slender, which can give people a softer and more comfortable feeling. In addition, the air outlet area is minimized, the wind speed is maximized, and the airflow is more concentrated, which can quickly cool down the target within a smaller range.

[0067] When the diffuser component 203 rotates 22.5°, the diffuser plate 203b leaves the partition plate 202b, and the diffuser plate 203b shield moves to the half of the vent 105 (as shown in FIG13). At this time, half of the airflow passing through the vent 105 is discharged through the half of the vent 105, and the other half is discharged through the holes on the diffuser plate 203b. The airflow discharged through the vent 105 will maintain a large flow output, and the formed airflow column is thick; and the airflow discharged through the diffuser plate 203b will be cut by the holes to form a smaller and dispersed airflow column. The airflow at this time is called a tertiary airflow, which has some advantages of the primary airflow and the secondary airflow, so it can be used in a comfortable and slow cooling environment in a large range of space.

[0068] By changing the position of the rotating diffuser component 203, the device can provide at least three airflow output trajectories, thereby being able to meet different usage requirements and further improving the practicality of the air conditioning unit.
